Patented Oct, 1.4, 1930 PATENT I OFFICE JOSEPH BAB'IA, OF MARTIN'SFERRY, OHIO TUB Application filed August 14, 1929 Serial No. 385,730.

My invention relates to tubs, and more particularly to such tubs as areespecially adapted for rinsing clothes, dishes, or other articles whichhave been previously washed.

When such articles are rinsed in a tub, the

water contained therein soon becomes contaminated with the dirtyresidual wash water from the articles Washed which results in theformation of a scum of dirt and grease on the top of the water and acorresponding decrease in the rinsing etliciency thereof.

According to the present invention, I prevent the rinsing water fromthus losing its etticiency by the provision of means-for cone tinuouslyremoving the scum from'the surface of the water while articles are beingrinsedin the tub.

An object of the invention isto provide a tub with inlet means adjacentthe bottom thereof for continuously introducing the water into the tub,and outlet means adjacent the top of and extending substantially aroundthe tub 'for draining water therefrom at the same rate at which itenters, and at the same time efiectively removingthe scum from the topof the water. Other objects will become apparent from .a reading of thefollowing description, the appended claims, and the two viewsillustrated in the drawings, in which:

Figure 1 is a top plan view of a tub embodying my invention; and

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

In the drawing, whichillustrates a practical embodiment of my invention,there is shown a rinsing tub A, generally oval shaped in cross sectionand including a bottom 1, side walls 2, and end walls 3. The side andend walls are curved and merge with each other to form a continuous wallto be generall referred to throughout the remainder o the descriptionand i'nthe claims as'a side wall. The bottom wall 1 is provided aroundits outer edge with a U-shaped seat. 4 in which the lower edge of theside wall is positioned, the side wall being secured in the seat 4 bysolder, rivets, or other suitable means.

For reasons to be hereinafter set out in detail, it is desirable thatmeans he provided for admitting water to the tub adjacent its bottom andfor discharging or draining ofi water from the tub adjacent its top. Tothis end I provide inlet means generally designated B in the bottom ofthe tub and outlet means C adjacent the top thereof and extending aroundthe side wall.

The inlet means B includes-a coupling 5 comprising a body portion 6 anda peripheral flange.7 adjacent but spaced from the upper end thereof.The upper end of the coupling is positioned in an opening 8 in thebottom of the tub, and the peripheral flange 7 is arranged to abutagainst'the bottom 1. Rivets 9 passing through the flange and the tubbottom serve to securely connect" the coupling 5 to the tub bottom 1,although the couplin 5 may be secured to the tub by other suita'le meanssuch as solder. The coupling is hollow throughout its len h, thusproviding an inlet opening 10 for t e tub and the lower end portion ofthe body 6 is exteriorly threaded to receive a hose'coupling 11 on aflexible water supply hose 12.

In some locations, it is often diflicult to procure rinsing water whichis absolutely free from entrained dirt, and, in order that any suchmatter present in water flowing in through the hose 12 be prevented fromentering the tub, Iprovide a strainer comprising a plug 13 having itslower or outer end portion threadably mounted within the coupling 5 andits upper or inner end portion extending into the tub, the plug having alongitudinal passage 14 extending inwardly from the outer end of theplugand open to the interior of the tub at the inner end of the plug,and a lateral passage 15 extending through the inner end of the plug andcommunicating with the assage 14 and with the interior of the tub. lheinner end portion of the plug is substantially ball shaped, this ballshaped portion being disposed adjacent a flange 16 which abuts againstthe bottom of the tub when the plug is screwed into place. Intermediatethe ball shaped end of the plug and the flange 16 is a recessedcircumferential seat 17. A strainer cloth 18 is positioned over theinner end of the plug and over the seat 17 and is held in place by meansof a string or wire 19 which passes around the cloth and the plug and,when drawn tight, binds the cloth in the seat 17. Any solid mattercontained in the water entering through the hose 12 will be preventedfrom passing into the tub by means of the strainer-cloth, and if theamount of sediment in the water is great, so that the strainer clothbecomes-clogged up, the cloth may be readily removed for cleaning orreplacement without its being necessary to empty the tub.

The means C for discharging water from the tub includes an outwardlycurved portion 19 formed in the side wall and extending completelyaround the tube and a perforate ring 20 shaped to conform throughout itslength to the inner face of the side wall and having an inwardly curvedportion 21 spaced from the adjacent side wall portions to form adischarge conduit 22 which is fixed with relation to and which extendscontinuously around the side wall. The outwardly curved section 19 ofthe side walls is provided with an outlet, connection 23having flanges23; se-

- cured to the section 19. The connection 23 is formed with a tubularthreaded outer end to receive a hose coupling 24: on a flexible hose 25.

In order to provide a strong and durable connection between the sidewall of the tub and the ring 20, the walls are formed with a seatextending completely around the tub and comprising spaced upper andlower aligned seat portions 26 and 27, respectively, which receiveflanges 28 and 29 on the ring 20 extending respectively above and belowthe curved portion 21 thereof. The side wall of the tub is also providedwith a pressed rib 30 upon which the lower edge of the flange 29 rests.The ring 20 is secured in position in the seat in the side wall by meansof solder, rivets, or other suitable means.

In order to effect a continuous removal of the scum from all parts ofthe surface of the water it is necessary that all of the surface waterbe kept moving. To cause this movement of the entire surface of thewater, a continuous or substantially continuous horizontal dischar eopening extending substantially around t e-tub must be provided, since,if only a single opening located at one point in the side wall is used,only that part of the surface water which is closed to the opening willbe kept moving and the dirt and grease on other parts of the surfacewill form as a film which will adhere to the side Wall and consequentlywill not be removed from the tub. For this reason I provide the ring 20with a series of spaced openings 31 of restricted area which arearranged in a common horizontal plane and which, as a series, extendsubstantially around the tub. When water is su lied to the tubcontinuously through t e iiose 12, it will finally reach a levei littleabove the bottom edges of the openings 81 and will then flow into theconduit 22, from which it will be drained through the hose 25. Since theopenings 31 collectively extend all around the tub, water will drainfrom all points of the surface to the sides of the tub and willconsequently keep the surface scum moving so that no film of scum willbecome lodged against the tub side wall. By using a series of individual0 enings of restricted area, the velocity of t e water flowing towardsthe openings is greater than it would be if a single openin or slotextending completely around the tu were provided, and the scum will beeffectively broken and will readily travel with the water out throughthe openings.

If water should be introduced into the tub at a rate somewhat greaterthan normal, the openings 31 might not present sutficient area to allowthe water to drain off as fast as it enters. For this reason I providethe ring 20 with another series of spaced openings 32 extendingsubstantially around the tub and disposed in a plane above the plane inwhich the openings 31 lie. In order to'avoid weakening of the ring 20through the cutting of a multiplicity of openings therein, the openingsof the lower series and the openings of the upper series are staggeredwith respect to one another. It is obvious that if water isadmitted tothe tub more rapidly than it may flow out of the lower series ofopenings, it will rise until it reaches the upper series of openings, atwhich time the openings of the lower and upper series will togetherprovide a discharge area suflicient to discharge wafoter at the samerate at which it enters the tu From the foregoing it will be apparentthat a tub embodying my invention greatly simplifies the work of rinsingpreviously washed articles of various kinds. The rinsing operation maybe completely erformed in a single tub which is always ull of cleanwater. When using my improved tub it is not necessary to empty the tuband refill it several times, as is the case with ordinary tubs.

I claim:

1. A tub comprising a side wall; a bottom; an inlet opening for said tublocated adjacent the bottom thereof; a discharge conduit extendingaround said side wall adjacent the top of the tub and having an innerface forming a portion of said side wall; a lower series of spaceddischar e openings in the inner face of said conduit and extendingsubstantially around the tub in a common plane; and an upper series ofspaced-discharge openings in the inner face of said conduit andextending substantially around the tub in a common plane above the planein which the lower series lies.

2. A. wash tub comprising a side wall; a bottom; means for admittingfluid to the tub adjacent the bottom thereof; a horizontally disposedrecessed seat extending around the inner face of the side walls; and aring shaped to conform to said inner face of said side wall and havingspaced flanges positioned on said seat, said ring having a perforateintermediate portion spaced from the side wall of the tub and oonjointlyforming therewith a conduit extending around the tub.

3. A tub comprising a side wall; a bottom; discharge means in said sidewall adjacent the top of the tub and extending substantially around thetub; an inlet opening in the tub;

a plug having its outer end portion mounted in said opening and havingits inner end portion extending into the tub; a passage in said plugextending inwardly from the outer end thereof and having an inner endarranged to communicate with the tub adjacent the bottom thereof, saidplug being provided with a recessed seat located between the inner endof the passage and the outer end of the plug;
